Steiner was riding his motorcycle east on Mojave Drive at about 100 miles per hour on Aug. 29 when he struck a Nissan Sentra that was trying to turn left onto Mojave Drive from Amethyst Road, sheriff's officials said.

Steiner was an organ donor and matches were found for his kidneys and liver.

"Although Stephen's death is a tragedy to those who love and miss him, they are comforted knowing that others will live because Stephen had so generously checked the donor box on his DMV paperwork," said family friend Becky Milburn.

Steiner suffered traumatic injuries including the loss of his right arm, various broken bones and several internal injuries, officials said.

The driver and passenger of the Nissan were only slightly injured and did not require medical attention.
